. VIOLIN FRICTION-PEG.

Application filed July 22, 1913.

To all whom it may concern:

Be it known that we, NELSON B. BAILEY and IGNAZ A. LUTZ, a citizen ofthe United States and a subject of the Emperor of Austria-Hungary,respectively, and residents of the city and county of San Francisco,State of California, have invented a new and useful Improvement inViolin Friction-Pegs, of which the following is a specification. Ourinvention relates to friction pegs for violins wherein bearing platessecured to the peg-box, are provided with sockets and are frictionallyheld between rounded shoulders on the peg and on one end of a sleevethereon, and the objects of our invention are, first, to provide afriction peg that will not slip and relieve the tension of the violinstring secured thereto, second, to provide inclined bearing plates thatare adapted to lie at various angles to the peg and to engage theslanting Walls of the peg boX, and third, to provide a simple andeffective construction that may be secured to the peg-box of any violinwithout defacing the same or enlarging the holes therein.

F or a full and clear comprehension of our invention reference should behad to the drawings forming a part of the present specification whereinlike numerals of reference designate similar parts throughout the saidspecification and drawings, and in Which Figure 1 is the front elevationof the neck of a violin, disclosing the friction pegs in position andthe violin strings secured thereto. Fig. 2 is an enlarged verticalsectional view through the peg-box taken on a line parallel with one ofthe pegs. Fig. 3 is an enlarged front elevation of one of the bearingplates rotatably mounted upon the square stem. Fig. 4 is a sectionalview of one of the bearing plates disclosing the pins which engage theside of the peg-box for the purpose of preventing the plate fromturning.

The purpose of our invention is to provide a peg that will not beloosened by the tension of the violin string that is secured to it andyet may be easily turned for the purpose of regulating the tension of ortuning the said string.

The peg-box 1 is provided with the usual apertures for the reception ofthe pegs. The peg 2 is provided with a rounded shoulder 2' and a squarestem 3, having a thread- Specification of Letters Patent.

ed portion 3 at the outer end thereof. A sleeve 4 is also provided witha rounded end 4 and is further provided with a square central bore thatis adapted to receive the square stem 3 of the peg 2, the purpose ofwhich will be hereinafter more fully described. Inclined annular bearingplates 5 are provided with the concaved seats 6 and the pins 7 androtatably mounted on the stem 3. A suitable nut 8 is threaded onto theend 3 of the stem 3 for the purpose of retaining the sleeve 4 thereon.The squared portion of the stem 3 is further provided with a slot 9, anda diametral aperture 10 in the sleeve 4 is adapted to coincide with aportion of the said slot so that the violin string may be insertedthrough the said aperture and slot. In order to effectively engage thecommon tapered violin peg the alined apertures in the opposite walls ofthe peg-box are made one slightly larger than the other.

In providing a violin with the improved friction peg the inclinedbearing plates 5 are placed one on each side of the larger aperture. Thestem 3 of the peg 2 is inserted through the central opening in eachplate 5 and the sleeve 4 is slipped onto the said stem 3 before the endthereof enters the smaller hole in the opposite side of the peg-box 1.In placing the sleeve 4 on the stem 3 the said sleeve is turned so thatthe hole 10 therein will coincide with a portion of the slot 9 of thesaid stem 3. The slot 9 in the stem 3 is provided for the purpose ofpermitting the sleeve 4 to be moved longitudinally upon the said stem 3without obstructing the passage of the violin string through the hole 10of the said sleeve 4. After the sleeve 4 is in position the threaded end3 of the stem 3 is inserted through the smaller hole in the oppositeside of the pegbox 1 and the nut 8 is screwed thereon. By screwing thenut 8 against the sleeve 4 I the concaved seats 6 of the bearing plates5 are engaged between the rounded shoulders 2 and 4 and the pins 7 arepressed into the side of the peg-box 1. The bearing plates 5 are thussecured against rotation and the combination of the rounded shouldersand the concaved seats permits the said plates to be inclined and toadapt themselves to the slanting sides of the walls of the pegbox. Thepressure of the rounded shoulders against the bearing plates may beregulated and adjusted by means of the nut 8 until the desired rigidityof the peg is obtained.

It is obvious from the foregoing that we have provided a friction pegfor violins that may be efiectively secured against loosening and theconsequent reduction in the tension of the violin string securedthereto. We have also provided inclined bearing plates that may bereadily adapted to the various slants of peg-boxes.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent is- 1. The combination with the peg box of aviolin, of a peg having a rounded shoulder and a stem extending beyondthe shoulder; a sleeve having a rounded end and slidably mounted uponthe stem; inclined bearing plates rotatably mounted upon the stembetween the sleeve and the rounded shoulder of the peg, said platesbeing arranged one on each side of the slanting walls of one side of thepeg box; and a nut secured to one end of the stem and adapted to causethe bearing plates to be tightly engaged between the rounded shoulder onthe peg and the stem and to engage the slanting walls of the peg box.

2. The combination with the peg box of a violin, of a peg having arounded shoulder and a stem thereon extending beyond the shoulder; asleeve having a rounded end thereon and slidably mounted upon the stem;inclined bearing plates having concaved seats therein and rotatablymounted upon the stem, between the sleeve thereon and the roundedshoulder of the peg, the said plates being arranged one on each side ofone of the walls of the peg box; and a nut screwed to the end of thestem and adapted to cause the inclined bearing plates to be tightlyengaged between the said sleeve and the rounded shoulder of the peg, andto engage the slanting walls of the peg box.

3. The combination, with the peg box of a violin and a tuning peg havinga rounded shoulder and a stem thereon extending beyond the shoulder, ofa sleeve having a rounded end and slidably mounted upon the said stem;inclined bearing plates having concaved seats therein rotatably mountedupon the stem, one on each side of the peg box and between the sleevethereon and the rounded shoulder of the peg; and a nut screwed onto theend of the stem and adapted to cause the rounded shoulder and the end ofthe sleeve to tightly engage the concaved seats of the inclined bearingplates and the said bearing plates to engage the slanting walls of thepeg box.

4. The combination, with the. peg box of a violin of a tuning peg havinga rounded shoulder and a square stem having a slot therein; a sleevehaving an aperture and arounded end thereon slidably mounted upon thesaid stem, extending beyond the shoulder and the aperture within thesleeve being arranged to coincide with a portion of the slot within thestem; inclined bearing plates having concaved seats therein androtatably mounted upon the square stem, one on each side of the peg boxand between the sleeve thereon and the rounded shoulder of the peg; anda nut screwed onto the end and adapted to cause the rounded shoulder andthe end of the sleeve to tightly engage the concaved seats of theinclined bearing plates and the said bearing plates to engage theslanting walls of the peg box.

In witness whereof we have hereunto set our signatures in the presenceof two sunscribing witnesses.
